The Companion Animal Parasite Council (CAPC) recommends centrifugal flotation as the preferred method for routine screening of faecal samples for detection of parasite ova. Centrifugal flotation using sodium nitrate and/or zinc sulphate is our preferred parasite test method.

Centrifugal flotation for oocyst isolation using Modified Sheather's solution is our preferred method for cryptosporidium testing. The Companion Animal Parasite Council (CAPC) recommends centrifugal flotation as the preferred method for routine screening of faecal samples for detection of parasite ova.

At present we are performing studies regarding parasites in the captive environment and therefore the results could be used for publication purposes. The samples and information received shall be form part of our database and will be anonymous.

We are unable to discuss treatment regimes as per the Royal College of Veterinary Surgeons (RCVS) rules as the animals are not under our care. Footnotes shall be given and you should contact your veterinary surgeon regarding treatment. We also offer support for your veterinary surgeon if necessary. Further tests may be recommended in specific cases which may include PCR/ELISA.

Frequently asked questions (FAQs)


Disease caused by Cryptosporidium sp. in reptiles - Cryptosporidium varanii (saurophilum) and C. serpentis are the species of interest affecting reptiles. C. serpentis mainly affects the stomach and C. varanii affecting the small intestine (Lihua Xiao et al., 2004), although other locations have also been reported, including the inner ear (Frye et al., 1999) and pharynx (Uhl et al., 2001). Other species of Cryptosporidium have been detected and may cause disease.

It is considered and important disease in reptile collections, especially those involving Leopard Geckos and collubrid snakes.

Infection is via the faecal-oral route, either via the direct route between animals that are housed together, or indirect route through fomites or vehicles including keeper manipulation of animals, housing components, food. Risk of infection through these routes is considered high.

Oocysts are formed as the criptosporidia pass through the intestinal tract which are eliminated intermittently via the faeces. This can complicate diagnosis and is the reason why sequenced testing is reccomended to increase detection possibilities - or increase sensitivity.

CRYPTO DETECTION COMPLICATIONS • Oocysts are eliminated intermittently which may reduce detection through one single test • Asymptomatic carriers: animals that do not show any signs even after long quarantine periods

COMMON SIGNS/SYMPTOMS Diarrhoea, maldigestion-malabsorption syndrome, anorexia, cachexia, death. The importance of asymptomatic carriers is exacerbated in those cases where a male is introduced to numerous females.

DIAGNOSIS Different tests are available including ELISA, immunochromatography, PCR, staining techniques and immunofluorescence - each with their pros and cons - read more. It has been proven that a modified Ziehl Neelsen test is an efficient diagnostic method and even the chosen method of diagnosis according to some studies. Let us remember that although other techniques or tests such as PCR may be very efficient, that shedding is intermittent and therefore ideally sequenced tests should be performed.

A negative diagnosis should not be based solely upon one test results. The Centers for Disease Control and Prevention (CDC) advise that at least 3 samples should be tested before a negative result is reported (CDC link). We consider this as a minimum and consider that up to six samples should be tested for highly valued reptiles.

A modified Ziehl-Neelsen technique and fluorescence microscopy are our preferred primary diagnostic methods.

In some cases it may be necessary to determine the species of cryptosporidia ie in cases of rodent eating monitors or snakes.

TREATMENT Treatment and elimination of infection is unrewarding. The infected animal should be isolated from a group or not introduced if tests positive during quarantine. Different drugs have been used to control clinical signs.

PREVENTION • Strict quarantine period of 2 months • Strict hygiene • Sequenced specific testing: Reptiland-Crypto-Testing
